Genes affected
TCF23 (HGNC:18602): (transcription factor 23) The gene encodes a member of the basic helix-loop-helix transcription factor family. Studies of the orthologous gene in mouse have shown the encoded protein does not bind DNA but may negatively regulate other basic helix-loop-helix factors via the formation of a functionally inactive heterodimeric complex.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 14, 2022The c.479G>A (p.R160Q) alteration is located in exon 3 (coding exon 3) of the TCF23 gene. This alteration results from a G to A substitution at nucleotide position 479, causing the arginine (R) at amino acid position 160 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
